a" corporation of ltiichigan ApplicatiomFebruarym,1940, Serial; News I 1- Claim. (01. 189- 75) The invention relates to" casing constructions and refers more particularly to metal window casing constructions for use especially in build:- ings;

The invention has for one object to provide a casing construction which can be shipped knocked down and can be readilyattached. to a window frame in the field without tools which are special or diillcult to handle.

The invention has for another object to provide a casing construction. which is attachable to a standard construction of window frame.

The invention has for furtherobjects to pro-- vide a casing construction having its sections individually attachable to their'respective frame sides by a; relative transverse movement and to provide a casing construction having its sections secured to their respective frame sides by elements bent into securing relation.

These and other objects of the invention will become apparent from the following description, taken in connection with the accompanying drawings, in which t Figure l is an elevation showing a metal window frame" from the inside and the severalsec- 'f tions of the casing detached from the window frame and each other;

Figures 16, 17, 18 and 19 are views. similar to Figure 3 showing modified constructions ofmy invention.

In general, the casing construction-embodying my invention comprises aiplurality. of sections corresponding respectively to the several. sides of the window frame and of a width corresponding to the distance from the window" frame to the inside of the wallto which the window frame and casing are applied. The sections; are, preferably formed of sheet metal and provided at their inside edges with flangesswhich are. adapted tooverlap the wall and form. a plaster ground and trim.

As illustratedin Figures, 1, 2 and3, ll isa metal;

window frame of standard construction having its sides formed of the relatively narrow barsv 2 which are welded or otherwise securedto each other'at the corners to form a rigid structure. In the present instance, thebarsareof a Z cross section having the outside and inside flanges.E 3 and. 4- respectively; the intermediate web 5: and the beads fi and I on opposite sidesof the web from the outside-flanges and inside flangest respectively. The window frame is adapted tobe anchored in i the wall through the, outside flanges andalso the window frame isionly a fraction-of the width of the. wall in which it is mounted.

The casing construction supplements the window frame and is formed of the sections 8, 9-, I0 and, H which correspond respectively to the several bars forming the bead, silland jambs of the window frame. Thesections are formedof sheet metal and have at their inside edges the plaster ground and trim flanges 1-2; All the sections have. their ends fashioned for interengagement with each other, the upper and. lower sections 8: and 9 being formed at their ends with, the

flanges l3 for overlapping the end portions of the jambsections Hi and II and the'jamb sections'being provided with the tongues l4- which are bent over the end portions of the upperand lower sections, thereby looking all of the sections together. The tongues maybe either integral with the:jamb sections or permanently attached theretoasby. riveting; welding, or other method; .(For attachingthe, casing to the window frame; the casing; sections are individually engageable with their respective frame bars by a movement transverse to the; window frame followed by a movement parallel to the window frame, Figure 3' illustrating in dottedlines the position of: the casingsectiontf after it has been moved transversely of the window frame. For'interlocking the casing sections to their. respective framezbars; each casing section is formed with the transverse portion l5. which. extends longitudinally thereof and whichforms a: shoulder forengag ing and, cooperating with thershoulder formed by the inside face of the bead l of the respective ing forming cooperating engaging shoulders for limiting transverse movement of the casing section relative to the frame bar in an inward direction. The tongue may be either integral with or permanently attached to the casing section as by riveting, welding, or other method. A number of such tongues for each casing section are provided, the number depending upon the length of the casing section. A corresponding number of openings l8 are also provided, these openings being elongated and extending longitudinally of the frame bar and preferably having a length greater than the width of the tongue to allow for slight inaccuracies in the positioning of the tongues.

As illustrated particularly in Figure 3, each tongue [6 is angle-shaped and has one flange overlapping and permanently secured to the offset portion ll of the casing section, the other flange being straight. After the casing section has been moved in a direction parallel to the frame and the tongues I6 passed through the openings I8, their free ends are bent over to form the flanges l9 which overlap the web of the frame bar and serve to secure the casing section to the frame bar.

With this construction, it will be noted that the casing is formed of several sections which may be shipped knocked .down to occupy a minimum amount of space during transportation. At the point of erection the casing sections may be quickly assembled with the window frame, as above described, by individually engaging the sections with their respective frame bars and these casing sections may be secured to each other at their ends by bending over the tongues upon the jamb sections to overlie the upper and lower sections.

Figure 4 discloses another modification in which each casing section 20 is formed with the longitudinally extending transverse portion 2| which provides a shoulder for cooperating with and engaging the shoulder formed by the outside face of the inside bead 22. These shoulders cooperate to limit transverse movement of the casing section relative to the frame bar in an inward direction. Relative transverse movement in the opposite direction is limited by the tongues 23 engaging the outside edges of the openings 24 formed in the web 25 of the frame bar. The construction of the frame bars is the same as that of Figures 1, 2 and 3 and the method of assembly of the casing sections with their respective frame bars is the same, with the exception that the free ends of the tongues 23 "are bent in an outward direction to overlap the webs of the frame bars.

In the modification illustrated in Figure 5, each of the casing sections 26 is formed with the longitudinally extending hollow rib 21 which embraces the inside bead 28 and with the longitudinally extending elongated openings 29 outwardly beyond the hollow rib. Each window frame bar is formed with the integral tongues 30 struck out from the web 3|. The tongues during assembly of the casing sections are straight and extend at right angles to the web to pass through their respective openings 29 in the casing section. With the casing section in place, the tongues are bent in an outward direction and serve, in addition to securing the casing section to the frame bar, to hold the casing section from transverse movement relative to the frame bar in an inward direction. It is apparent that the inside wall 32 of the hollow rib cooperates with the inside bead 28 of the frame bar to hold the casing section from transverse movement in an outward direction.

As shown in Figure 6, each of the casing sections 33 is formed with thelongitudinally extending transverse portion 34 which cooperates with the inside bead 35 of the associated frame bar to limit transverse movement of the casing section in an outward direction. The outer edge portion of the offset portion 31 of each casing section is formed with elongated openings through which pass the tongues 38 suitably secured to the web 39 of the associated frame bar, the free end of each tongue being straight and extending at right angles to the web during the assembly and then being bent over in an outward direction. It is apparent that the tongues cooperate with the outside edges of the openings to limit transverse movement of the cas'mg section relative to the frame bar in an inward direction and also that the bent over free ends of these tongues serve to hold the casing section to its associated frame bar.

Figure 7 discloses another modification in which each of the casing sections 40 i provided at its edge with the longitudinally extending hollow rib 4| which is adapted to embrace the inside bead 42 of the associated window frame bar. The web 43 is formed with the struck out tongues 44 which during the assembly extends at substantially right angles to the web to permit assembly of the casing section with the frame bar, after which the tongues are bent downwardly to clamp the outside wall of the hollow rib against the outside wall of the inside bead.

The construction disclosed in Figure 8 is similar to that of Figure 7, with the exception that the tongues 45 are formed separately from the Window frame bars 46 and are adapted to be suitably secured thereto as by welding, riveting, or other method. The casing sections 41 are formed in the same manner as the casing sections 40 and are also assembled in the same manner, the tongues 45 during assembly occupying the positions shown in dotted lines. After assembly, the tongues are bent down over the hollow rib.

Figures 9, 10 and 11 disclose another modification in which the casing sections are individually engageable with their respective window frame bars by a movement transverse only thereto. Each casing section 48 is formed with the longitudinally extending transverse portion 49 which forms a shoulder for cooperating with the shoulder formed by the inside face of the inside bead 50 of the associated frame bar 5!. The offset portion 52 of each casing section is formed with the integral tongues 53 which before assembly are bent at an angle, as indicated particularly in Figure 11. The offset portion is also formed inwardly beyond the tongues with the openings 54 having a width substantially equal to the width of the shanks 55 of the lugs 56, which latter are struck out from the web of the frame bar. These lugs are formed with the heads 5! which are of greater width than the openings 54 to extend over the offset portion 52 and hold the same toward the associated frame bar. The openings formed by bending the tongues 53 to the position shown in Figure 11 are sufficiently large to enable moving the casing section transversely of the associated frame bar in an outward direction without interference by the lugs. When the transverse portion 49 has been moved into contact with the inside bead, the lugs are then 10- cated in the openings 54 and the tongues 53 may then be bent back into their original planes to cooperate with the lugs in preventing transverse movement of the casing section relative to its associated frame bar in an inward direction.

Figure 12 discloses another modification in which each of the casing sections 58 is formed with the longitudinally extending transverse portion 59 forming a shoulder for cooperating with the shoulder upon the inside bead 68 of the associated frame bar 6|. Each casing section has secured thereto a plurality of sheet metal tongues 62 which during assembly extend parallel to the offset portion 63 of the casing section and are adapted to extend through the elongated opening 64 formed in the outside flange 65 of the frame bar. After the casing section has been moved into place, the free ends of these tongues are bent over against the outside face of the outside flange and serve to prevent relative movement of the casing section'in an inward direction. It will be noted that in this construction the casing sections are individually engageable with their respective frame bars by transverse movement only.

The construction of Figure 13 differs from that of Figure essentially in securing each of the casing sections 66 to their respective frame bars 61 by separate tongues 68. As shown, each casing section is provided with the longitudinally extending hollow rib 69 for embracing the inside head 18 of the frame bar and the tongues 68 are originally formed to have an angle section with one flange overlying the marginal portion of the casing section and the other flange extending through the elongated opening H formed in the web of the frame bar, the free end of this latter flange when assembly has been completed being bent over to overlap the web, thereby securing the associated casing section and frame bar together. i

As disclosed in Figures 14 and 15, each of the casing sections 12 is formed with the longitudinally extending transverse portion 13 which forms a shoulder adapted to enage and cooperate with the shoulder formed by the inside face of the inside bead 14 of the associated frame bar 15. In this case, the tongues 18 are formed integral with each casing section and during assembly are adapted to extend transversely thereof to pass through the openings I1 formed in the web of the frame bar. After assembly, the free ends of the tongues are adapted to be bent over to overlie the web. In this construction, the edges of the tongues and the openings may be depended upon to prevent relative transverse movement of the casing section and frame bar, if desired.

Figure 16 discloses a construction which is similar to that of the final form of construction illustrated in Figures 1, 2 and 3. In this construction each of thecasing sections 18 has the longitudinally extending transverse portion 19 for cooperating with the inside bead 80 of the associated frame bar 8|. Each casing section has permanently secured to its offset portion 82 the channel shaped tongues 83 which are adapted to extend through the elongated openings 84 in the web of the associated frame bar and to overlie the web. The flanges at the free ends of the tongues are of a size to pass through the openings during assembly which is accomplished by moving the casing section parallel of its associated frame bar when the casing section is at an angle, as indicated by dotted lines in Figure 16, and by then swinging and bodily moving inwardly the casing section to its final position after the flanges at the free ends of the hooks have been passed through the webs of the frame bars.

Figure 17 shows a construction which is the same as the final form of construction illustrated in Figure 4. The method of assembly is similar to that of Figure 16 in that each casing section is individually engageable with its associated frame bar 86 by moving the casing section parallel to the frame bar with the casing section at an angle, as indicated by dotted lines in Figure 17, until the flanges 81 at the free ends of the tongues 88 have passed through the openings 89 in the web of the frame bar, after which assembly is completed by angularly swinging the casing section and bodily moving the same outwardly.

Figure 18 discloses a construction similar to that of Figure 5 in which each casing section 98 is adapted to be individually assembled with its frame bar 9| by a movement parallel to the frame and then by a swinging movement. The parallel movement engages the openings 92 in the casing section with the. tongues 93 struck out from the Web of the frame bar and the swinging movement then compels the hollow rib 94 of the casing section to embrace the inside bead of the frame bar. I

Figure 159 discloses a construction similar to that of Figure 6 in which each casing section 95 is individually engageable with its respective frame bar 96 by a movement parallel to the window frame and then by a swinging movement. The first movement causes the flanges 91 at the free ends of the tongues 98 to pass through the openings 99 in the casing section and the second movement then places the casing section in its proper desired relation to the frame bar.

In all of these various forms, the casing sections are secured to each other at their ends in the same manner as the casing sections of Figures 1, 2 and 3.

What I claim as my invention is: v

The combination with a frame comprising a plurality of side bars, of a casing attachable to said frame comprising a plurality of sections corresponding respectively to said side bars and individually engageable therewith and extending thereover at one side, said side bars and sections having cooperating shoulders for limiting relative transverse movement of said side bars and sections in one direction, said side bars having openings therethrough, and means upon and unitary with said sections extending through the openings and over said side bars at the side opposite said sections for securingsaid casing in place on said frame, said means being engageable with edges of the openings to limit relative transverse movement of said side bars and sections in the opposite direction.
